Technical comment on 2.5 Parameters. It says:
Additionally, if a p:pipeline does not declare any parameter input
ports, but contains a step which has a primary parameter input port,
then an implicit (and unnamed) primary parameter input port will be
added to the pipeline.
I thought we'd agreed that an implicit primary parameter input port will
only be added to the pipeline if one of its contained steps has a
parameter input port.
